A bloodied European royal’s only concern after getting socked in the face at a trendy nightclub was that he not suffer the indignity of being taken to a “crappy” hospital.

Princess Grace Kelly’s grandson Pierre Casiraghi was walloped so hard by businessman Adam Hock that a witness “saw him literally flying and landing on a table of glasses,” according to a new report.

Casiraghi’s jaw caught the edge of the table, and the glasses on top shattered, according to an account in the latest Vanity Fair.

“There was blood and glass broken all over his face,” the witness added.

Casiraghi was quickly escorted out of the Meatpacking District’s Double Seven lounge when a bystander called 911.

On a recording of the call, Casiraghi can be overheard worrying “if they’re gonna bring me to this crappy place,” referring to Big Apple hospitals.

Hock, the former owner of the Hawaiian Tropic Zone, pleaded guilty two months ago to disorderly conduct for clocking Casiraghi and his pals on Feb. 18, 2012.

And in a matter of days, Casiraghi will drop his civil case against Hock — and The Post has learned that no money will exchange hands.

“They got nothing. I guess they felt it wasn’t worth pursuing. The case has been dismissed,” said Hock’s lawyer, David Motola.

Now Vanity Fair has a literal blow-by-blow of the brawl, illustrated with previously court-restricted, time-stamped surveillance video of the high-society clash.

Ceiling-camera footage reviewed by the magazine shows a crowded club with leggy models dancing between tables, where Casiraghi and his European party are squeezed into a bottle-service table with Hock and his party shortly before 2 a.m.

There is some dispute over who has rights to the complimentary $450 Grey Goose bottle on the table, provided by club partner Jeffrey Jah.

“Since you can’t afford a bottle, I’ll buy one for the table,” a Casiraghi friend said, according to the magazine.

In the video, Casiraghi pours himself a shot of the vodka, and seconds later Hock’s first punch flies.

The first Casiraghi friend hit was Diego Marroquin, 33, a Mexican-born real-estate investor.

Next up — or down, as it turned out — was Vladimir Restoin Roitfeld, 27, the son of a French fashion empress.

Then Casiraghi, 24, rushed over.

He is hit and reels backward into a low, jagged-edged wood table, the video reveals.

Then another Casiraghi friend, Stavros Niarchos, 26, a Greek shipping-tycoon heir and one-time Paris Hilton boyfriend, runs over and approaches Hock, only to be sent two steps back with a punch to the jaw.

Unclear, at least from the video, is what provoked Hock, who The Post reported was defending the honor of the women being groped at his table.

The Post’s story featured a photo of a shirtless Hock with a bruise on his arm, and recounted testimony from model witness Shawna Christensen, who said one of the Europeans had swung a vodka bottle at Hock during the fracas.

Vanity Fair took a crack at the The Post’s exclusive coverage, saying Hock was “portrayed . . . as a self-made knight of the round V.I.P. table, protecting the virtue of supermodel maidens against the lordly predations of a gang of jetsetting, table-coveting toffs.”

An enhanced video of the fight shows something “light and elongated” swinging down toward Hock’s head from behind.

“The DA dropped the criminal case, and clearly they wouldn’t have done that if there had been an assault of the kind that the Casiraghi side is claiming,” Tacopina said.

In prior press statements, Tacopina has brushed off the Casiraghi contingent as “international bar brawlers,” and “four drunk guys who make a living trying to get their names in the papers.”

Although the dropped court cases seemingly put an end to the sordid tale, Hock keeps coincidentally encountering Casiraghi’s entourage, the magazine noted.

Hock last summer entered a nightclub in Paris where the guests included Casiraghi’s brother, Andrea.

Hock was asked to leave.

Months later, Roitfeld was eating with his girlfriend and another couple outside Bar Pitti, on Sixth Avenue in the Village, when Hock sat down at the adjacent Da Silvano; Roitfeld’s party quickly paid the check and left.

Adding to the discomfort is the relationship between the models on both sides of the dust-up and Rotfield’s Paris Vogue editor mom, Carine Roitfeld.

Model Natasha Poly was with Hock’s party at the Double Seven. She reportedly sent a text to Roitfeld’s mother that said she “got pulled into a situation out of our control.”

As for Casiraghi and his hospital hangup, he was treated at New York-Presbyterian, where he needed stitches to close a gash in his cheek.
